Grub2 + Qemu does not use new acpi

I am developing an x86_64, multiboot2 compliant OS (with grub2) and testing it on Qemu. When I run it, the multiboot2 only contains tag 14 (old acpi e.g. v1) not 15 (new acpi e.g. 2.0+). The host machine is a Mac OS X late 2016 with an Intel Core i5 and should be using the new ACPI. I am running qemu with the following flags: -m 8G -boot d -cdrom $(iso).
Ideally, I would like to see ACPI v2.0+ tables so I can use an HPET (for example).
Qemu Version:
$ qemu-system-x86_64 --version
QEMU emulator version 2.12.0

Grub2 Version:

/usr/local/grub2/bin/grub-mkrescue (GRUB) 2.03
osx grub2 qemu acpi
